excludedURIs

The finite set of namespace URIs that are almost completely excluded from
the set (that is, each namespace URI that included in the set with with
a finite number of QName exceptions). Null if the set of namespaceURIs
that are almost completely included is infinite.

Null (meaning almost all URIs excluded) if includedURIs() is non-null;
non-null otherwise.

The finite set of namespace URIs that are almost completely included in
the set (that is, each namespace URI that included in the set with with
a finite number of QName exceptions). Null if the set of namespaceURIs
that are almost completely included is infinite.

Null (meaning almost all URIs included) if excludedURIs() is non-null;
non-null otherwise.

excludedQNamesInIncludedURIs

The finite set of QNames that are excluded from the set within namespaces
that are otherwise included. Should only contain QNames within namespace
that are within the set includedURIs() (or any URI, if includedURIs()
is null, which means that all URIs are almost completely included).

includedQNamesInExcludedURIs

The finite set of QNames that are included in the set within namespaces
that are otherwise excluded. Should only contain QNames within namespace
that are within the set excludedURIs() (or any URI, if excludedURIs()
is null, which means that all URIs are almost completely excluded).
